    Tip: Optimise images

    We estimate potential to save at least 450kB* by optimising images:

    1. costa%20rica%20jungl... is 2.6MB
    2. Dual-HP-Studeny-camp... is 385kB and could be 268kB smaller
    3. ribbon-study-homepag... is 220kB
    4. Extreme-weather-tran... is 207kB
    5. dual-homepage-workwi... is 177kB and could be 148kB smaller
    6. Campus-news-grid.jpg is 132kB
    7. support-us.jpg is 109kB and could be 15kB smaller
    8. Underwater-air-bubbl... is 104kB and could be 19kB smaller
    9. COP28-Young-Climate-... is 96kB

    First, check that images are appropriately sized - you most likely don't need a 6000x4000 pixel image straight from a digital camera. In Windows, the Photos software will let you quickly shrink huge images and will give you an improvement.

    Next you could try using tinyjpg.com (JPG image) or tinypng.com (PNG image) to further optimise your image. This will strip out metadata that may be taking up lots of space.

    *This is an estimate from Google PageSpeed and you may get much better results than this in practice.

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Cookiebot uses 127kB
    2. YouTube uses 80kB

    Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading.
